THE PROVINCIAL WATER POLICY PLAN FOR GELDERLAND
EXPERIENCES FROM THE NETHERLANDS 165 THE PROVINCIAL WATER POLICY PLAN FOR GELDERLAND : DOES IT LEAD TO PROPER GROUNDWATER MANAGEMENT? E. Romijn Romijn Consultancy, Mariënbergweg 1,6862ZL Oosterbeek. The author is grateful for information received from Mr A.G.G. Heeren, Project Manager of the Department of Water and Flood Protection, Province of Gelderland. The author, however, is solely responsible for this article. Introduction Integrated water management started in the Netherlands when the "Wet op de waterhuishouding" (Law on Water Management) was passed in 1988. Integrated water management received its shape with the publication of the national Third Document on Water Management (1989) and the first generation of Provincial Water Policy Plans, the one for Gelderland appearing in 1991. Studies on integrated water management, however, had already started in 1970. I The present situation in groundwater management can only be understood within its historical context. Four periods can be distinguished: 1900-1920: The establishment of regional water supply companies; groundwater is preferred as a resource because of its good quality; 1920-1940: Problems of public water supplies are steadily increasing in the western part of the Netherlands due to the scarcity of suitable groundwater and surface water resources; the first proposals for water legislation are rejected, mainly for economic reasons; 1945-1970: The prognosis of the demand for water in the year 2000 leads to extensive surveys to reserve "the last drops" of groundwater for water supplies; the Water Undertakings Groundwater Act (1954) and the Law on Physical (Town and Country) Planning (1962) are used for water planning; extensive programmes of drainage and land improvement are implemented to develop modern agriculture; 1970-1995: Completion of legislation on water and the environment; creation of a system of national master plans (structuurschema's,nota's);ecological and environmental assessment studies on groundwater abstraction and pollution. During the first period (1900-1920), the Central and Provincial Governments stimulated the establishment of regional undertakings for public water supplies, the shareholders of which would be the local communities. The use of groundwater was preferred because of its good and safe quality. In the lower western part of the Netherlands, however, problems arose because fresh groundwater resources are mainly restricted to the dune areas, the polder areas generally having brackish water. Soon the dune water resources were exhausted, while urbanisation deteriorated other surface- and groundwater resources. Proposals for legislation on groundwater abstraction (1923), sewerage systems (1925), and the protection of potential water resources against pollution (1940) were rejected as being not (yet) feasible. During the second period (1920-1940), when problems in the western part of the Netherlands grew, studies were conducted by the Central Committee for Drinking Water Supplies, an 166 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE advisory committee to the State. The studies (1940) included resource evaluations and forecasts of population growth and per capita water demand in the year 2000. Both were underestimated by 40-50%. Interesting is that State Public Works, State Forestry, and a consultant for Nature Conservation participated in this Committee, whereas agriculture was not represented. In the third period (1945-1970), agriculture underwent a rapid development. From 1960 onwards, some very rainy years showed that, if agriculture were to be modernised and mechanised, extensive land drainage and improvement works were needed, especially in the higher sandy parts of the Netherlands. These works were duly implemented. Meanwhile, the Drinking Water Sector warned that these works could result in water scarcities because future additional groundwater abstractions would lead to a further lowering of the watertable. These conflicts led to the installation of the Study Committee for the Water Management of Gelderland in 1970. The resulting study is regarded as one of the first steps in developing integrated water management; it included water quality and ecological problems as well. Meanwhile, groundwater legislation, originally used to enforce groundwater abstraction for water supplies, was now used to restrict groundwater abstraction. After 1970, environmental problems came to the attention of the decision-makers. Nitrate pollution of groundwater became well known. Legislation on surface water pollution (1970) and soil protection (1986) followed. Environmental Impact Reports were enforced from 1987 onwards. The very dry year 1976 (frequency 0.3%) caused an explosive development of sprinkler irrigation, although it became clear that, in the long run, sprinkling of grassland is not 'economically sound. Again groundwater abstractions increased. In 1987, a general "dehydration" of wet nature reserves was recognised as a major problem. Since the appearance of the first Water Policy Plan ( Waferhuishoudingsplan~HP1990) in 1991, five years of experience had been condensed in the second Water Policy Plan for Gelderland (WHP 1996). Meanwhile, the Water Boards had published their integrated plans for the three parts of Gelderland: The "Veluwe", situated north of the Lower-Rhine and west of the IJssel rivers; "Eastern Gelderland" situated east of the Rhine and IJssel rivers; The "River Region", between the Lower-Rhine and Meuse rivers. I , This gives us the opportunity to evaluate: The development and integration of the separate plans for groundwater and surface water into one "overall" plan and policy; The integration of physical (town and country), environmental, and water planning and policy (omgevingsbeleid); The co-operation with local communities and Water Boards and the involvement of various interested parties; The realisation of objectives and standards; The implementation of water management by Water Boards and water supply companies; Costs and benefits of the water policy and its implementation; Monitoring of the water system. 167 I II Brief description of the First Water Policy Plan for Gelderland (WHP 1990) Integratedwater management I The Water Policy Plan (WHP) is an integrated policy plan for water management in the Province. It deals with directives for the development and protection of the water systems, including "natural" and "technical" structures for both groundwater and surface water. (National rivers and canals are excluded.) "Integrated" means that it includes earlier plans for the improvement of surface water quality and for groundwater abstractions. The WHP has to be "attuned" vertically to the water policy of the Central Government, at the same time giving directives to the Regional Water Boards (waterschappen) and the local communities. It also has to be attuned to the Provincial Physical (Town and Country) Plan, and the Provincial Environmental Plan (which includes soil protection and the sanitation of polluted soils). In 1989, about NLG 208 million were spent on water management in Gelderland: 150 million for the improvement of surface water quality, 90% of which was financed through "the polluter pays" principle; 56 million for the control of surface water levels, mainly paid for by the owners of land and buildings; 2 million for the control of groundwater abstraction, of which one-third was covered by the water supply companies (to maintain a monitoring network for groundwater levels) and about two-thirds by the Provincial Government, which used to be the groundwater manager. Calculated over a provincial population of 1.8 million, the total water management costs of NLG 208 million mean NLG 115.- per inhabitant. For 1995, the yearly water costs were calculated for a "standard" household using 135 m3 drinking water per year. These costs included those for dyke maintenance, for the sewerage system, and for the drinking water supply, and amounted to NLG 790.- per household. Today, as the household water use is 135 litres per head per day, this means that the standard householdconsists of 2.75 persons. The W HP 1990 pointed out the following main problems: Water nuisance (groundwater levels too high) in various western and northern parts of Gelderland and in several cities; Drought damage (groundwater level too low) mainly in the eastern part of Gelderland and around the Veluwe; agriculture and nature reserves both suffered; Eutrophicationof surface water and the need for research on micro-pollutants; The need for research on sometimes heavily polluted aquatic sediments; General pollution of groundwater by agriculture, acid rain, urban areas, etc.; The inadequacy of the surface water system to sewe nature protection or recreation. The WHP distinguishes long-term goals (25 years) and short-term policies and actions (4 years) to reach these goals step by step. The long-term policy receives its form by assigning to each region a specific "water function". A water function indicates for which purpose this part of the water system might be used (e.g. for agriculture, drinking water, or nature reserves). The water functions indicate the water level and the water quality by specifying the requirements for the proposed use within the constraints of the water system. The water system cannot produce more water than is available unless it is "over-exploited". In fact, the Province of Gelderland declares as its main goal: 168 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE "To develop and maintain a healthy water system which guarantees a sustainable (continuous) use of water for humanity and nature." This fits very well within the idea of sustainable development. As the water systems have been deteriorating during the last decades and have sometimes been over-exploited as well, the long-term policy means cleaning up the water systems and restoring their natural values. This will mainly be achieved by realising quantity and quality standards that apply for the entire province, the so-called "base level", which serves as a minimum requirement. Special attention is being given to the protection and rehabilitation of the water-related nature areas (e.g. along brooks and rivers). As all drinking water in Gelderland is produced from groundwater, protecting groundwater against pollution is of the utmost importance. The base level The quality standards are called "general environmental quality standards" and are prescribed by the Central Government in its Third Document on Water Management (1989) as "Quality Objective 2000". For surface water, for example, standards for total phosphate are 0.15 mg P/I and for total nitrogen 2.2 mg NA. There are standards for heavy metals and for micropollutants, not only for surface water but also for the sediments on the bottom of rivers and canals. As base level for groundwater quality, the drinking water standards of the European Community apply. For example, for nitrate 25 rng NOJI (= 5 7 mg NO,-NA) and as maximum permissible 50 mg NOJI (= 11.3 mg NO,-NA). As to the groundwater flow, the regional flow systems should be conserved and surface water levels should be kept as high as acceptable in order to reserve water for dry periods. Flooding, however, should be prevented. The water functions Besides the "base level", the following water functions are distinguished: I II, Ill, IV V VI VI I Vlll IX X XI XI1 Xlll Water for agriculture; Complex of water for agriculture and nature reserves. The importance of nature reserves increases from II towards IV; Water for nature reserves which have the highest ranking; Groundwater for drinking water supplies; Groundwater for industry and services; Water in urban areas; Water for landscape and historic sites; Water for boating recreation; Water for fishing recreation; Water for swimming; Water for navigation. All functions have their proper requirements as to water levels. For example, wetlands (wet nature reserves) require higher groundwater levels than agricultural land. EXPERIENCES FROM THE NETHERLANDS 169 Groundwater is primarily reserved for drinking water because of its good natural quality. Groundwater abstraction for drinking water is guaranteed to a maximum of 170*106m3/year. In 1988, these abstractions amounted to 136*1O6 m3and in 1994 to 157*1O6 m3/year. The budget for private groundwater abstractions (industry and services) is 85*1O6 m3/year, the abstractions in 1994 being 77*1O6 m3. In nature reserves (Function V), negative human influences should be negligible. I In urban areas, land subsidence caused by a lowering of the watertable should not take place. Nevertheless, watertables should be deep enough to prevent problems of "water in the basement". Storm water overflow from the combined sewerage systems into surface waters should be reduced as much as possible by building retarding devices (e.g. detention basins) in order to achieve the "general environmental quality standards" in the brooks and rivers. Short-term groundwater objectives In this paper, only the groundwater items of the short-term programme (1991-1995) will be considered. A distinction should be made between "active" groundwater control by way of surface water level control (control of the drainage-base level) - as practised by the Water Boards - and "passive" groundwater control - as practised by the Provincial Authority with its licence system for abstractions. The following objectives apply: A general constraint is a stand-still principle of drought damage in nature reserves (Functions Il-V) caused by drainage works and groundwater abstractions, with 1985 as a reference year; In Functions I (agricultural areas) and Vlll (urban areas), groundwater levels shall be suitable for the normal use of the land (task of the Water Boards); In several nature reserves, drought damage shall be diminished (task of the Water Boards and the Provincial Authority, with subventions from the Central Government); Demand management shall stabilise groundwater use for households, services, and industry (Functions VI and VII). Groundwater of good quality shall not be used for lowquality purposes (e.g. for cooling water). For a further development of drinking water supplies, induced recharge or artificial recharge shall be taken into consideration (task of the water undertakings); Natural recharge of groundwater shall be increased (e.g. by reducing evapotranspiration through the replacement of conifers with deciduous trees, by the infiltration of rainwater in urban areas, etc.) Budget WHP 1990, period 1991-1995 The budget for the WHP 1990 activities amounted to NLG 27.5 million, to be paid by the Central Government (9 million), the Province (8.5 million), the Water Boards (10 million), local communities, and water supply companies. About NLG 6 million was to be spent for groundwater management (active as well as passive control). Evaluation of the WHP 1990 During the period 1991-1995, emphasis was mainly given to: The creation of RegionalWater Management Plans by the Water Boards (completed in 1995); The re-organisationof the Water Boards into larger "all-in" (quantity + quality control) 170 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE Water Boards; Putting pressure on regional projects for integrated water management. At the end of 1995, only half of the foreseen activities had been implemented and only half of the Provincial budget (NLG 8.5 million) had been spent. Bottlenecks, especially for the rehabilitation of wetland reserves, were: obtaining the land area and compensating farmers for wetness damage due to the watertable rise needed for the nature reserves. The quality management of surface water is outside the scope of this paper. The WHP 1996 New developments The long-term policy as to water functions is still in line with WHP 1990, although differing essentially on the abatement of drought damage to nature reserves ("dehydration"). A national analysis of groundwater levels over the period 1950-1986 showed that: In the higher sandy parts of the Netherlands, an average regional drop in levels of 0.2 m had taken place; In land consolidation areas, the average drop was 0.35 m; Locally, groundwater abstraction had led to a drop of 1 m or more. Parliament, .after discussing the "dehydration" as described in the Third Document on Water Management (1989) (through the Motion Lansinwan Rijn-Vellekoop) decided on a reduction in the area of "dehydration" by 25% in the year 2000, as against the situation in 1985. This 25% reduction policy had to be included in the new WHP 1996. The Province, however, decided to aim at a reduction of 10-15% for 2000 instead of 25%. In the WHP 1996 (period 1996-2000), emphasis is being placed on: Optimal surface water control for all interests involved; Protection and rehabilitationof wet nature reserves; Sustainable groundwater supply to households and special industries that need highquality water; - Urban water control. - All the above-mentioned items have implications for groundwater management. Priority is being given to what are known as "action zones", which are areas abundant in nature, mainly situated around the Veluwe, in eastern Gelderland, and the Gelderse Poort. Special attention is being given to a better implementation of the foreseen activities. Groundwater The financial consequences of the WHP 1996 (period 1996-2000) amount to NLG 655 million, of which about NLG 150 million is related to groundwater management, as follows: Shifting 25% of groundwater abstractions for drinking water, services, and industry from the Veluwe to less-drought-sensitive areas: NLG 64 million; 25% reduction of other abstractions (de-watering building sites, sprinkler irrigation): NLG 35 million; Replacing 2500 ha of conifers with deciduous forest on the Veluwe: NLG 1O million; Regional integrated projects for "dehydration"abatement: NLG 28 million; EXPERIENCES FROM THE NEfHERLANDS 171 Wetness abatement in urban areas: NLG 13 million. In Gelderland, the groundwater abstractions registered in 1994 were: Water supplies: 157'1 O6 m3; Industry and services: 77'1 O6 m3; De-watering of building sites: 32*106m3; and Sprinkler irrigation 27*106m3. So a total of 293 million m3. A total of NLG 148 million has been calculated as the cost of decreasing "dehydration". As a consequence of the actions listed in the WHP 1996, the "standard" household will be charged NLG 950 in the year 2000 (in 1995: NLG 790). Evaluation of the provincial groundwater management The various subjects listed for evaluation at the end of the Introduction will be briefly considered here. Integrated water management The WHP 1990 and the WHP 1996 both showed great progress in integrating policies for surface and groundwater, both their quantity and their quality. The "active" and "passive" groundwater control is still in different hands (the Water Boards and the Province, respectively). The need for strong co-operation between authorities and organised groundwater users (water supply companies, industries, agricultural organisations such as the landbouwschap) is a main theme and strategy in the WHP 1996. Integration of town and country planning, and environmental and water planning The different plans within the Provincial Government are currently in the stage of being integrated by the simultaneous development of these plans. Maps and key issues are attuned, as are the enforcement of legislation and the monitoring of the efforts of different participating authorities and private parties. Examples of key issues are: Sustainable (environmentally-friendly) urban and industrial development; Sustainable (nature-friendly) agriculture; Efficient traffic and transport. Cooperation with water boards, local authorities, local communities, and water users in implementing the water policy According to the WHP 1996, all "water actors" are now involved in the planning process, which took about three years. In this way, the Province expects to achieve better acceptance of its water policy and therefore a better implementation of the WHP 1996. The Province expects that, by allocating tasks and responsibilities, a "bottom-up" process will be started, which will lead to the realisationof the assigned water-functions. 172 ILRI WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE Costs and benefits The costs, especially those of "dehydration"abatement, were mentioned earlier. The drinking water costs, which are directly related to groundwater management, would rise by 10% or about NLG 0.20 per m3. This, at least, is less than the general tax of NLG 0.35 per m3 imposed on groundwater by the Central Government. This tax is not specifically used for water purposes, but is aimed at discouraging groundwater abstraction. The benefits will be better groundwater management, mainly for nature reserves and also for urban areas. Monitoring I During recent years, a monitoring network for the quantity and quality of surface water and groundwater has been set up. It is maintained by the Water Boards and the water supply companies. Concluding remark The question asked in the title -whether the WHP's lead to proper groundwater management - can be answered in the affirmative for the instruments developed for planning, control, and monitoring. However, whether the policy objectives - which have been stated by the Central and Provincial Governments - are proper and realistic (especially those for "dehydration"), only time will tell.

Schrevel ILRI, Lawickse Allee 1 1, P.O. box 45, 6700 AA Wageningen (email: schrevelQilri.agro.nI) Introduction The afternoons of days 1 and 2 of the workshop were spent in working-group sessions and in plenary discussions. Each participant was asked to join two working groups. Eight working groups were formed, each with one subject to discuss. Examples of subjects were "Appropriate Economic Policy Instruments", and "Required Levels of Decision-Making". The conclusions of the working groups were reported to all participants during reporting sessions. The reporting sessions were followed by plenary discussions. To structure discussions, each working group was asked to concentrate on three questions and to formulate answers to these questions in relation to the subject of the working group. The questions were identical for each working group. These were the questions to be answered: - is it relevant to distinguish between different situations or conditions? - what should be considered the optimum situation? - how can the optimum situation be achieved, given the prevailing conditions? Thus, the working group discussing "Appropriate Economic Policy Instruments" would first determine whether different economic policy instruments are required under different conditions. It would then proceed with determining the optimum mix of economic policy instruments. Finally, it would discuss appropriate action to achieve the optimum situation that had just been formulated. The working group on "Required Levels of Decision-Making'' would go through the same sequence, but would of course focus on its own subject. Not all working groups could complete the discussions in the relatively short time that was available to them. Other working groups allowed discussions to proceed in a less structured way, thereby not necessarily focussing on the core questions. As a consequence, the three core questions were not covered completely in all cases. So instead of presenting the answers to the core questions in this report of the workshop, we present the main conclusions as reported by the working groups, and the reactions to these by other workshop participants. In some cases, inconsistencies were found in what was concluded for,one subject in relation to another. This will not surprise anyone, when it is realised that the topic of groundwater management is not only relatively new, but also highly complex. No attempt has been made to hide these inconsistencies in this report. Nor, for that matter, has any attempt been made to present discussions and conclusions more favourably than they actually were. All working group reports and plenary discussions were recorded on tape and were typed out after the workshop. The conclusions of the workshop were also obtained from this material. 174 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE The management themes Objectives of groundwater management An absolute objective of groundwater management does not exist. It is not possible to say that groundwater management should always achieve one particular goal or set of goals. It all depends on the agreement between those involved in decision-making on what is to be achieved. This is the main conclusion of the discussions on the objectives of groundwater management. Extreme solutions are possible. To give an example, a society could agree on extracting more water from a groundwater resource than could possibly be recharged, thereby agreeing to mining, and eventually to depleting the resource. This could be justified by arguing that the benefits obtained through this policy are used to restructure the economy. Other forms of capital could thus be created - forms of capital that can be put to work once the groundwater resource is depleted. Such a policy would be fully justified, workshop participants argued, provided it is embedded in well-argumented and consistent development plans. One could choose not to agree with this approach, but universally-valid arguments against it do not exist. It all depends on the choices made. Or in Otto's words (quoting Smith), "There is no real answer to the question of what is good groundwater management. The answer depends upon what values a system seeks to maximise. Or, one might well ask, whose values?" (Otto, this volume, page 48). The example shows another point on which workshop participants agreed: the priority of groundwater management need not necessarily be to safeguard the physical integrity of groundwater resources. Economic objectives can override environmental objectives. A further conclusion was that proper groundwater management should not look at groundwater resources in isolation from surface water resources, but should look at all water resources in relation to each other. This is only logical because the hydrological relationships between groundwater and surface resources are many, and dynamics of groundwater resources cannot be understood unless seen in relation to those of surface water resources. An approach integrating groundwater with surface water is always required, regardless of the development stage of a society or country. Groundwater management objectives depend on the conditions.in a country. For example, a country embracing groundwater management for the first time may decide to start with mapping hydro-geological features in an effort to gain an insight into the potential of groundwater resources. As the papers on Yemen, Egypt, and Kenya show, this is indeed a choice that is frequently made. Another society may consider it necessary to prioritise access to groundwater by all, including the poor, thus putting emphasis on a priority of socioeconomic development. Another example put forward in the discussions is a society that prioritises the use of groundwater for distinct uses (e.g. drinking water). Notwithstandingwhat has been said above, the optimum situation was considered a situation in which environmental conditions are sustainable (i.e. they are not deteriorating), and priorities for the use of groundwater are consciously set. Workshop participants argued that a distinction needs to be made between fossil groundwater reserves and renewable reserves. The former can be exploited, if it is accepted that eventually the resource will be depleted. The latter can be used as well, but a preference CONCLUSIONS OF THE WORKSHOP 175 existed among workshop participants in favour of avoiding over-exploitation. It was concluded that a maximum of only half, or a third, of the net annual recharge should be abstracted each year. A related point came up later in the discussions. It is interesting enough to be mentioned here, even though it may confuse matters. Eventually, all groundwater resources tend to some state of equilibrium, even reserves that are at present being over-exploited. Under conditions of over-exploitation, groundwater tables will fall and abstracting water will consequently become more costly. As a result, fewer users will be able to lift water and total abstractions will decrease, until the point is reached that annual abstractions are equal to annual recharges, at which moment a new, lower-level equilibrium has set in. This argument was brought forward in reaction to the statement that a balance needs to be maintained between abstractions and recharges. The question is: a balance at what level of equilibrium? Required levels of decision-making Two principles of natural resource management surfaced during the discussion on the most appropriate levels of decision-making. The principles were: 1. The institution with a mandate to manage a natural resource should have jurisprudence in an area larger than the area covered by that resource; 2. Management decisions should always be taken at the lowest appropriate level. The second management principle was first formulated in a World Bank report, and refers to managing natural resources in general (see paper by Schrevel, this volume). Note that it says "the lowest appropriate management level", not "the lowest possible management level", which is something entirely different. It is these two forces, which can work in opposite directions, that determine decision-making levels. More concretely, central governments should set priorities, but should refrain from getting involved in detailed matters. Provincial levels should integrate all water sources in their management activities and decisions, as well as economic and other factors. Local levels, including water users, should be involved in decision-making. ' Transparency in institutional mandates and decision-making was mentioned as being important in achieving good groundwater management. Excellent data bases on which to make decisions, and sound legal frameworks within which to make decisions, were further considered important. On this occasion, as well as on many others, the need for awareness among decision-makers and users about the properties of "their" groundwater resource was stressed (see further below). Good governance, law, and administration Law and administration systems in many countries facing intensified groundwater exploitation are as yet inadequate to cope with quickly changing situations. Even in those cases where laws do exist, these often date from times when groundwater was not used as intensively as at present and when pollution was not the threat that it often is today. New laws are being written, but do not always provide the solutions to problems that groundwater users are facing. In the case of Baluchistan in Pakistan, sensible local initiatives were even frustrated by the introduction of a new law (Steenbergen, this volume). A core problem is undoubtedly 176 ILRI WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE 1, law enforcement. Administrative systems are not equipped for the successful enforcement of existing rules and regulations. The cases of Yemen, Pakistan, and Kenya are all examples of the lack of adequate legislation and groundwater administration. Much energy is being invested in these countries today in efforts to formulate adequate legislation. , The discussion on good governance, law, and administration concentrated on the ten rules for groundwater control as formulated by Otto (see page 58).Because of the lack of time, only the first of these rules was subjected to discussion. Otto's first rule for groundwater control says that a legal limit must be put on the quantity of groundwater that a landowner can bring to the surface. The discussion that followed focused on minimum conditions that must be fulfilled before such a rule can be effective. The rule itself was not challenged. The geographical focus was again on conditions in a semi-arid country. For Otto's rule to be successful, the following conditions were listed: Groundwater users must first experience problems before regulations to limit water abstractions can be successful. Examples of problems are dry wells and the reduced success of neighbouring landowners in lifting water; - Hydro-geological conditions must be known before the maximum abstractable quantities of water can be determined; a land classification system that reflects hydro-geological conditions must be put in place; - The general public, and groundwater users in particular, need to be aware, or be made aware, of the acute nature of the threat to their groundwater resources. In fact, it was broadly felt that awareness creation is an absolute condition for successfully limiting groundwater abstractions by individuals. - An optimum situation is only possible if insight exists into the hydro-geologicalconditions in a country, and into the dynamics of groundwater use. The latter aspect includes an insight into how much water is being used, by whom, where, and for what purposes. An insight into groundwater use has not received much attention as yet, not even in countries that have benefited from foreign aid projects. An optimum situation further entails an effective system of law and administration. Here, "effective" means not only adequate laws, but also includes proper procedures to effectuate laws and organisations to enforce them. Participants further felt that groundwater management is preferably entrusted to strong, existing organisations, rather than to a new organisation created for this purpose. - In achieving optimum conditions, existing land and administration systems first need to be analysed. An answer must be formulated to the question of whether, and to what extent, these are adequate. In a parallel effort, hydro-geological conditions must be mapped and groundwater use must be analysed. Economic and other policy instruments The discussion on economic policy instruments was an exceptionally lively one. This may be a reason why not all matters raised could be brought to a conclusion. 1 CONCLUSIONS OF THE WORKSHOP , 177 A general feeling prevailed that water pricing (i.e. putting a price on a unit of groundwater and making groundwater users pay that price), although a recommendable policy, is difficult to implement. Practical problems in using this instrument were the main reasons for hesitation, and sometimes for downright disapproval. Two main objections were raised. The first was the impossibility of the task of determining a price for groundwater. How much would it have to cost? Which price level could be said to be a fair reflection of its scarcity, or of its importance as a life-supporting component in ecosystems? The second problem concerned the many practical problems involved in collecting the amounts due. In some area, literally thousands of small farmers are using pumps and are abstracting groundwater. Practical economists among the participants had answers to at least some of the objections raised. Thus, it was stated that indirect pricing was possible. The cost price of groundwater to users is equal to the costs of lifting water to the surface and applying it for its intended use. These costs include depreciation costs of the pump, and the costs of energy to operate the pump. A levy could be put on either the purchase price of the pump or on energy, which is usually diesel or electricity. This, however, is less straighlfoward than it seems, because these inputs are applied to other processes as well. It was argued that, particularly under conditions of scarcity, a levy on pump operation costs would be effective, because it would help to reduce abstractions. It was further suggested that operating costs should be increased by a kind of tax. From this tax, research on groundwater resources and groundwater use could be financed. Increasing the cost of lifting groundwater by means of a levy or tax would work to the disadvantage of poorer groundwater users. This was seen as a problem and was discussed in terms of a choice between efficiency and equity. It was felt that governments have to strike a balance between efficiency and equity. Overall agreement existed on at least one point. Where subsidies still exist on diesel or electricity, as is the case in India and Pakistan, these should be abolished. In one case, an exception would be permitted: this is when a government decides to support poorer sections of rural populations. A subsidy on their energy costs would effectively increase their spending power. In addition to these direct and indirect ways of water pricing, a different category of economic policy instruments was discussed. These are the macro-economic policy instruments. Governments could do much to promote certain crops and discourage the cultivation of others. To reduce groundwater abstractions, high water-demanding crops could be discouraged (e.g. by taxing them). This would effectively reduce the demand for those crops. In Yemen, for example, the government should ban the import of low water-demanding food crops, thus stimulating the cultivation of these crops in Yemen itself. In these cases, farmers would be less inclined to grow high water-demanding crops. The objection was raised that these measures work well in a relatively small country like Yemen, where climatological conditions are homogenous and agro-ecological zones few. In countries like Pakistan and India, however, where climate and crop-growing conditions are highly different from one part to another, such measures would not work. They would have positive or neutral income effects in one part of the country, and negative effects in another part. (The element of scale is all too often neglected in discussions on proper groundwater management.) 178 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE Roles of users, politicians, and groundwater experts A distinction needs to be made between conditions of an abundance of groundwater and conditions of its scarcity. Where groundwater is abundant, users can pump as they please, but governments are well-advised to start mapping groundwater reserves and to monitor them. Under conditions of abundance, communication between the parties involved need not be intensive. The situation is different under conditions of scarcity and intensive use. More important than anything else is good communication between politicians, users, and groundwater experts. Institutions that can facilitate communication should be set up (see below). In the discussions, the diverse categories of politicians were divided into politicians at the level of central government, politicians at lower levels, and government officials. At the central-government level, politicians were said to have the task of setting rules and developing legal frameworks. They are also responsible for developing long-term strategies. Lower-level politicians work these out for their respective regions. In this way, the overall framework within which decisions on groundwater use and control are made, are formulated at central-government level. Decisions on actual groundwater use should be the mandate of the lowest appropriate levels (see also under "Required Levels of Decision-Making", above). The role of government officials is to control adherence to agreed rules and regulations. Groundwater users should be involved in management decisions. The role of groundwater experts (i.e. hydro-geologists) was not spelled out in detail. All that was said was that groundwater experts were to feed decision-makers with information on groundwater resources and how these change with time. Note that groundwater experts are not expected to take control decisions themselves. Good communication was considered extremely important. Different interest groups were recognised, including different groups of groundwater users (e.g. farmers and drinking-water companies), but also groundwater experts and even politicians. Each interest group has its own sources of information, its own understanding of the situation under the ground and on the ground, and its own interests to defend. Through communication, groundwater use and abuse could be controlled. The suggestion was made that users and groundwater experts ought to sit down together and work out sensible solutions. These would then be communicated to the politicians responsible for decision-making. Defenders of this approach pointed out that users and groundwater experts have their own interests, and politicians have to defend the common interest. The way to achieve this situation is first of all to set up the institutions that facilitate communication, as outlined above. Finally, a note of warning was heard. Although, in some cases, organising users is possible, in other cases it is hardly possible at all because of the numbers of farmers involved. Organising farmers in the Punjab, Pakistan, means that literally millions of individuals need to be organised. The often-neglected factor of scale is again in play here. i rI CONCLUSIONS OF THE WORKSHOP 179 Data collection and monitoring i i i i i I i i For proper groundwater management, two sets of data are required: data on water resources - both surface water and groundwater; data on water use and water users. - For water users, data are required on the different categories of users. Profiles of user categories should be made (large landowners, small landowners, drinking-water companies, different groundwater-abstracting industries). This would allow an understanding of the behaviour of different groups of users. Data should not only cover present uses, but should also make predictions on future use. It is also important to identify any constraints that different categories of groundwater users are experiencing. t In different situations, different sets of data are required. In general, the more constrained a situation is, the more detailed information is required. This is true, because more detailed decisions need to be taken. In contrast, when groundwater is readily available and used only by a few users who depend on the resource only to a limited degree, data on groundwater and groundwater use can be more general. In between these two extremes, many other situations exist. Optimum data collection and processing are not achieved from one moment to another, but need to be developed over time. They mature with time, in response to demands for more data of some kind. The monitoring of groundwater resources and groundwater use and users should be an on-going process. The data that become available through the monitoring process need to be analysed. The analyses should show actual constraints or future constraints. This will call for corrective measures. Finally, it was remarked that, under certain conditions, data may have to be protected. An example was mentioned of a donor-funded project that could produce a map showing in detail the groundwater potential in an area. Such a map would be of great interest to farmers planning to sink a well. They could use the map to determine where to drill, thereby avoiding sinking a well that would turn out to be dry. Under conditions of unrestricted groundwater abstraction, this kind of information could lead to accelerated groundwater exploitation, which would not be in anyone's long-term interest. Preferable management regimes The question of preferable management regimes was approached by first identifying the criteria required to distinguish between different groundwater situations and management regimes. Because of lack of time, the issue could not be taken further. Criteria to distinguish between different groundwater situations were mentioned to be the relative scarcity of groundwater, the extent to which diversity of interests occur, and the degree of conflicts. For example, a groundwater management situation can be characterised by scarcity, highly diverse interests, and a high degree of conflicts. At the other extreme is the case of abundant groundwater reserves and few people interested in it. Other combinations are possible. It was assumed that each of the different groundwater situations requires its own management regime. Note that in this view, it is not the hydro-geological conditions that determine the kind of management regime that is required, but economic and social-political conditions. 180 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE For comparison, the reader is referred to the paper by Nibbering. Nibbering works out the consequences of three different management regimes in terms of long-term benefits to groundwater users. The first regime is the open-access regime. The second is the situation of continued open access. And the third is the situation where groundwater is used under a common-pool arrangement. Under the common-pool management regime, all groundwater users benefit most in the long run (Nibbering, this volume, page 25). Training and dissemination of information Training is felt to be badly needed. A lack of insight is widespread among those involved in groundwater management. The lack of insight is certainly not restricted to users. Also politicians, and even groundwater experts, can profit from training. These are also the target groups that were defined by the workshop participants: politicians, groundwater experts, and users. Training should be directed not only to specific target groups, however, but also to the general public. National public campaigns should be organised to make people aware of the danger of over-exploiting groundwater resources and of polluting them. India's successful national public campaign to explain the properties of another natural resource (i.e. forests) was mentioned as an example. Discussing the subjects that need to receive attention in training, the participants stressed the point that these should reflect local conditions. Results from on-going monitoring of local groundwater resources should be ploughed into the training material. Prevailing institutional arrangements and procedures should be explained as well. A frequently-encountered problem was mentioned to be that data often exist, but are not shared with others. Or if they are reported, that they are often not used. In addition to training, the transfer of information between parties was considered to need improvement. Not only should reports be sent to decision-makers, a dialogue on the meaning and consequences of their contents should take place as well. A few remarks were made regarding the costs involved in training and the dissemination of information. It was said that these should be borne by the government and by the users. But bilateral or multilateral organisations could be helpful in setting up appropriate facilities and routines. Training should be conducted by - foreign or domestic - research institutions. These institutions have data available. They are also best placed to organise training (although groundwater institutes as yet do not systematically collect and disseminate information on groundwater use and users!). li 1 .I I I'! CONCLUSIONS OF THE WORKSHOP 181 Epilogue The discussions produced conclusions that were not presented under one of the above headings, or that have general relevance. Thus, it was said that underlying the discussions of the workshop was the assumption that societies in developing countries would allow the democratic approach favoured by the workshop participants. This would not always be the case in reality. One is therefore advised to accept that the recommendations of the workshop require adjustment to prevailing political conditions. Four conclusions were heard again and again throughout the two days of the workshop. They deserve to be repeated here. They are: - not only should hydro-geologicaldata be collected, but also data on groundwater use and users; this is not yet taking place routinely, as is clear from the case studies; - groundwater should not be looked at in isolation, but in relation to surface water; groundwater management should be part of integrated water management efforts; - groundwater users need to be made aware of the condition of the resource on which they depend; and finally, - groundwater managers - politicians, experts, and users - need training to make them better aware of groundwater conditions in their environment and to teach them appropriate management policies. 1 j j I The workshop on "Groundwater Management: sharing responsibility for an open access resource" looked at a broad selection of relevant management issues. It may not have produced conclusive answers to all issues raised. Yet, it is hoped and expected that the workshop has at least improved our understanding of some of the problems involved. 182 ILRl WORKSHOP: GROUNDWATER MANAGEMENT: SHARING RESPONSIBILITY FOR AN OPEN ACCES RESOURCE LIST OF PARTICIPANTS 183 List of participants WWW 1997 Name Organisation or Country Ir.
